These data were compiled for evaluating river-reach level plant water use, or evapotranspiration (ET), and vegetation greenness, or Normalized Difference Vegetation Index (NDVI), in the riparian corridor of the Colorado River delta as specified under Minute 319 of the 1944 Water Treaty. The seven reach areas from the Northerly International Boundary (NIB) to the end of the delta at the Sea of Cortez were defined for research activities. Also, these seven reaches are being monitored under Minute 323 of the 1944 Water Treaty. Additionally, these data were compiled for evaluating restoration-level evapotranspiration and vegetation greenness data in Reach 2 and Reach 4, as specified under Minute 323 of the 1944 Water Treaty. Objectives of our study were to measure the peak growing season ET and satellite vegetation index data, specifically using the Enhanced Vegetation Index (EVI) from Landsat, for the average of months in summer-fall (May to October) for the seven reaches, for the full riparian corridor, and for four restoration sites, from 2000 through 2020. The evapotranspiration data represent measurements of ET using the enhanced vegetation index (EVI), along with potential ET from meteorological station data in Yuma, Arizona. The vegetation greenness data represent measurements of enhanced vegetation index (EVI) Landsat imagery, and these EVI data were then used as an input for actual evapotranspiration ‘ET’, along with potential ET from meteorological station data in Yuma, Arizona. These data were collected using Landsat satellite data (30 m resolution) record from 2000 over the delta of the Colorado River starting near Yuma, AZ and continuing another 150km to the Sea of Cortez along the river corridor. These data were collected by Pamela Nagler, Ph.D. of the U.S. Geological Survey-Southwest Biological Science Center, and Armando Barreto-Muñoz, Ph.D. and Kamal Didan, Ph.D. of the University of Arizona, Vegetation Index and Phenology Lab. These data can be used to evaluate riparian vegetation community water use and vegetation greeness in the Lower Colorado River delta region where there is active restoration efforts. These ET and NDVI data depict a Landsat time series from three sensors over the 21-year period. The time-series data can be used by land and water managers to monitor spatial and temporal riparian zone trends and changes, document riparian ecosystem health and its water use, and the impact of both drought, fire, land clearing and/or non-native species biocontrol in the riparian corridor of the Lower Colorado River delta. End users of these data are federal, state, tribal partners and NGOs on both sides of the International border.

These data were compiled for monitoring riparian zone trends and changes in the Lower Colorado Delta as part of the Minute 139 of the 1944 Water Treaty between the United States and Mexico. The quality and quantity of the Delta’s riparian and aquatic ecosystems have been dramatically reduced over the past century, due largely to significant alterations to natural hydrologic and sediment regimes. The Minute 319 Agreement states that 130 million cubic meters of water was to be released during the spring of 2014. Water was released from Morelos Dam at the Northern International Border (NIB) near Yuma, Arizona, to the river’s delta in Mexico, allowing water to reach the Gulf of California for the first time in 13 years since 2000. Our study evaluated the short and long-term effects of environmental flows to hydrological processes in this borderland delta region. Because of the landscape changes and the anticipated impacts of added water in 2014 from Minute 319 water release, we explored remote sensing-based change analysis techniques and data to develop time series data of the Colorado River delta riparian corridor vegetation greenness and water use since the year 2000. We divided the river into 7 Reaches (R1..R7) to separate between the different land covers, management conditions, and general geospatial and hydrological conditions. We generated a variety of vegetation index, ET, anomalies, and trends using time series for all reaches combined then separately. Our data shows Landsat and MODIS derived EVI and EVI2 as well as time-series data of ETLandsat-EVI (mm/day), using a modified (EVI mod) equation, and ETMODIS-EVI with both EVI and then EVI 2 as the input variable to the ET algorithm were extremely consistent across sensors and methods and covaried well with vegetation, climate, and hydrological conditions of each reach and the whole region.
